So a few weeks ago I re-did an old, empty brick planter - added some dirt and planted a few cacti in it. The dirt was scavenged from a pile just outside my fence. I can't remember where it came from originally, but it was dirt I dug out from someplace here and piled up outside the fence. So squash and tomato volunteers sprouted up all inside the planted from that old dirt. At least, I THOUGHT it was squash. Today those plants are blooming and instead of large yellow squash blossoms, it's tiny yellow blossoms. So I guess it's wild gourd or melon. I won't know until it sets fruit. I've been harvesting the leaves to feed my tortoises. I hope it's not toxic.
The plot thickens!
